APPARATUS EMPLOYED IN THE MANUFACTURE OF ARTIFICIAL SILK.

Application led September 5, 1919.

To @ZZ whom it my coni-cm:

Be it known that, I, JAMES CLAYTON, a

subject of the King of Great Britain, residing at 12 MiddlesboroughRoad, Coventry,

in the county of Warwick, England, have invented new and usefulImprovements in Apparatus Employed in the Manufacture of ArtificialSilk, of which the following is a specification.

My invention relates to machines .em-

ployed in the manufacture of artificial silk,

- sage of the thread into the spinning-box.

I have found that the operation of initially passing, or threading, Athethread through the thread-guide,` or funnel, is much facilitated,especially in cases where it is desired to run the machine at ahighSpeed, if means be provided whereby thethread is, during the threadingoperation, subjected to the action of a drawing-roller guide, or Godet,which has, during such operation, a circumferential velocity slower thanthat which the drawing-roller guide or .Godet has when the thread ispassing thereover on its way to the spinning-box during normal workingof the machine. My invention is especially adapted, for instance, foruse in an apparatus in accordance with m-y invention the subject-matterof application, Serial No. 309509, A. D. 1919, for Letters Patent, inwhich apparatus, the ordinary drawing-roller guide, or Godet, can be runso much more quickly than is done in Tdinary machines that, without someprovision according to my present invention, the/full advantage ofgreater Speed of outputwill not be practically obtainable owing to thedifficulty, of passlng the thread through the thread guides, or funnels,when the drawingroller guides, or Godets,are running at high Speed, butmy present-invention is not limited, in its application, to apparatus ofthis Specification of Letters Patent. y

particular kind as it can be employed with ordinary machines and enablethese to be run at higher speed than hitherto.

According to my present invention I p rovide means wher eby,`when thethreads are to be passed through the thread-guides, or funnels, the saidthreads can be passed over drawing-roller guides, or Godets, (all ofwhich I will refer to as Godets) caused to rotate at the required slowercircumferential speed. For this 'purpose I provide means whereby theGodets havedilferent species of rotation which I will describe, withreference to the accompanying drawings, premising that I do not limitmyself to the precise details illustrated.

Figure 1 shows`A in vertical transverse Section, and Figure 2 in sideelevation, sulicient of the upper part of a machine to yillustrate theapplication of my invention thereto when I employ an additional Godet,upon 7a shaft separate from that of the ordinary Godet, over which thethread passes, through the thread-guide, or funnel and into thespinning-boxwhen the machine is normally at work. Figure 3 Shows amodification wherein the additional Godet is connected to the ordinaryGodet.

.Like parts in all the figures Aare marked with the same referencenumerals.

Referring first to Figures 1 and 2, the spinning boX is marked 4 and the'threadguide or funnel is marked 17. The ordinary' Godet is marked C andis shown as being driven by a scroll-wheel n on the shaft N, engaging ascroll-wheel c2, on the shaft c, of the Godet C, which shaft c, iscarried in the long tubular bearing c1.

P, is an additional Godet, provided in accordance with my presentinvention. It

is shown as being mounted on the shaft 0' (carried in the long tubularbearing p1) which has on it a Scroll-wheel p2 which en-Y gages wit-hascroll-wheel g, on a Shaft Q,f[

which is driven, 'byany suitable gear at a slower circumferential speedthan that at which the Godet C is driven.y This can, for example,(assuming the Godets C and P to be, as shown, of equal diameter) beconveniently effected by reducing gear conveying motion from the Shaft Nto the shaft Q,-or, if desired, the additional Godet P can be of adiameter So muchsmaller than the diameter of the ordinary Godet C, thatthe Godros erts Cv and P can be driven at the same speed and have thedesired difference in rate of circumferential velocity.

I do not limit myself to any particular relative speeds, but I maymention that satisfactory results are obtainable if the Godet P bedriven. at a circumferential velocity of 125 feet per minute and theGodet.

ferred from the Godet P, to the Godet C, (asindic/ated at y in Figure Q)and coiling of the thread into the spinning-box` proceeds.

The troughs q1 and channels r2 are for carrying liquid which drips fromthe Godets, into the space below and thence away to any suitablereceptacle, or place.

InFigure 3 I have shown the additional Godet P formed in one with theordinary Godet C, but ofsuch smaller diameter that the Godet P will havethe required slower.

circumferential velocity.

What I claim is 1.!In apparatus for spinning artificial silk, orthelike, a spinning device and driven` roller guide means having differentperipheral speeds, and over which a thread may be passedLalternativelyat higherpor lower speed, to the spinning device, the roller guide oflower peripheral speed affording means which facilitates the initialfeed of the thread to the spinning device.`

2. In apparatus for .spinning artificial silk, the combination lof aspinning box, a guide funnel for leading thread into the spinning box,and driven guide roller means having different peripheral speeds, andover which a thread may be passed to the funnel alternatively at higheror lower speed, the roller guide .of lower peripheral speed-affordingmeans which facilitates the initial feed of the thread to the spinningdevice.

3.111 apparatus for spinning artificial` silk, a spinning box, a pair ofindependent guide rollers, and means for driving -the same at differentperipheral speeds' to.afford alternative feed means for leading a threadat higher or lower speed to the spinning box, the roller guide of lowerperipheral' speed aHording means which facilitates the initial feed ofthe thread tothe spinning device.

In testimony whereof 'I have signed my .name to this specification inthe ypresence of two subscribing'witnesses.
